To all it may concern:

Be it known that 1, WILLIAM. ML l-Linn' BAUER, a citizen of the'United States, I'QSlding at St. Louis, State of Missouriyhavef invented certain new and' useful Improvemerits in Valve-Spring Lifters, of which the ject the provision of a device having an adiralve piston, he stem of theslotted, lifter. arm to receivevalve, a circular socket to receive the lower following is a specification.

My invention-v relates to tools for com- ,pressing the springs on the stems of valves to permit a retaining nut or cross pin to be attached to the stem, and has for its objustable pin to engage the end of the valve spring, and a cam lever for actuating the lifter arm, the whole combining to comprise a very efiicient tool that is simple in construction and easy to operate.

vMy invention will be described in detail hereinafter and illustrated in the accomj panying drawings in which Figure the operatlug cam lever shown 1n an 1noperative position, Fig. 2,a top plan view,

Fig. 3, a view similar to Fig. 1 showing the cam lever in operative position applied to a v valve, and Fig. 4, a sectional detail of the spring engaging arm.

In the drawings similar reference characters will be used to designate corresponding parts in the several views.

lift-er is formed of a bar T-shaped in cross gjtion 2, having arms 3 and 4 on its upper and lower ends respectively. Arm 3 has its free end bifurcated as shown at 3, while' The frame 1 of my improved valve spring section, andconsisting 'of anupright porarm-4 is provided with an open slot 4* and a circular recess 5 in its upper face.

6 indicates a plate provided with a plate 6 upon its lower surface, and also provided with a notch 7 in one end to engage the upright 2 and is slidably mounted thereon.

8 indicates a screw threaded pin secured to the underside of plate 6, and .9 aniinteriorly' threaded adjusting thimble ma 1m;

ed on pin 8 and having its lower end tapered --as shown at 10.

. 11 indicates a lever fulcrumed in the bifurcated end of arm 3 and having a cam face -l2 and stop 13 that engages the upper side of plate 6 when in operation.

' My'device is adapted to be applied toa.

' 'valve structure A as shown in Fig.3. The 'fthi nble 9 engages the disk B, the plate 6 iengages the top of the casing and the plate 6* fits within the opening D in the valve casing and centers the device. The valve rod extends through the opening 4 .inthe ''arm 4 and the spring E is seated in the 'rearm of said U being rovided with a slot for the reception of a va ve rod and a recess for seating a valve spring, and a pin on said slidable plate adapted to engage said valve rod.

2. In a device of the character described, an upright, an arm extending from one end of said upright, said arm being provided cess 5. Whenthe cam lever is thrown from with a slot and a recess, a second arm extending from the other end of said upright, a cam lever pivoted upon said second named arm, a plate slidably mounted on said upright and adapted to be engaged by said cam lever, a screw threaded pin depending from said slidable plate, and a screw threaded thimble in engagement with said pin and adapted to engage a valve rod, said first named,- arm being adapted to engage alve 'spring.

formed upon the other end of said 3. In a device of the character described, a rigid supporting frame, a laterally extending arm formed upon one end of said frame, a cam lever provided with a stop and pivoted upon said arm, a slidable plate mounted upon said frame and adapted to engage a valve rod, a second laterally extendinig arm rame,

said second named arm being provided with a slot for receiving said valve rod and being 16 adapted to engage a valve spring.
